Title (EN) METHOD AND APPARATUS FOR STORING LOG LIKELIHOOD RATIOS IN INTERLEAVED FORM TO REDUCE HARDWARE MEMORY
(FR) STOCKAGE DE RAPPORTS DE VRAISEMBLANCE LOGARITHMIQUE SOUS UNE FORME ENTRELACÉE POUR DIMINUER LA MÉMOIRE MATÉRIELLE
Abstract: front page image
(EN)An apparatus and method for storing log likelihood ratios in an interleaved form comprising receiving a plurality of interleaved codewords (710); obtaining at least one log likelihood ratio (LLR) for the plurality of interleaved codewords (720); storing the at least one LLR in a memory (730); deinterleaving the plurality of interleaved codewords after the at least one LLR has been stored in the memory (740); and performing a bit decision of the deinterleaved codewords using the stored at least one LLR (750).
(FR)L'invention concerne un appareil et un procédé pour stocker des rapports de vraisemblance logarithmique sous une forme entrelacée comprenant la réception (710) d'une pluralité de mots de code entrelacés; l'obtention d'au moins un rapport de vraisemblance logarithmique (LLR) pour la pluralité de mots de code entrelacés (720); le stockage dudit LLR dans une mémoire (730); le désentrelacement de la pluralité de mots de code entrelacés après le stockage dudit LLR dans la mémoire (740); et la réalisation d'une décision binaire des mots de code désentrelacés à l'aide dudit LLR stocké (750).
